MACHINE FOR MAKING- IBOTTLES,

Application filed May '29,

To all/whom it may concern:

Be it known that I, WARREN E. GLASPEY, aeitizen of the United States,residing at Brid 'eton, in the county of Cumberland and tate of NewJersey, have invented a new and useful Machine for Making Bottles, Etc,of which the following is a specification.

This invention relates particularly to machines for making bottles, orsimilar containers, which are adapted to receive threaded stoppers, orstoppers equipped with thread segments; and the primary object of theinvention is to provide an improved machine for the purpose indicated,which is capable of large output, which reduces wastage. to a minimum,and which is economical in operation.

The improved machine, in its preferred embodiment, is adapted to providethe bottle or container, within the mouth ortion, with lugs, orthread-segments, WlllCll are adapted to be engaged by threads orthreads'egments With'which the stopper is provided. The stoppers may bemade of glass or other suitable material.

The invention is illustrated in its preferred embodiment in theaccompanying drawings, in which- Figure 1 represents a broken plansectional view of a bottle-making machine embodying the invention; Fig.1 a broken elevational view showing the upper partof the main standardof the machine, and a blow-head mounted thereon; Fig. 2, a brokenelevational view of the improved 'mac-hine; Fig. 2, a broken elevationalview showing a modification of the device for elevating the mandrels, insuccession; Fig. 3, a broken vertical sectional view taken as indicatedat line 3 of Fig. 7 Fig. 4, an elevationalview of a mandrel-tipemployed; Fig. 5, an enlarged edge elevational view ofone of thesheathable levers with which the mandreltip is equipped; Fig. 6, abroken elevational view, partly in section, showing a mold, theassociated mandrel, and the means for elevating the mandrels; and Fig.7, a view similar to Fig. 6 but showing the mandrel in the elevatedposition.

It may be stated preliminarily that a bottle-making machine of thegeneral type illustrated is known, such machine involving the use of arotary mold-car- 1922. Serial No. 564,597.

rier having invertible molds mounted on the carrier. The presentinvention relates particularly to the provision of means in connectionwith such a machine whereby bottles may be produced which have theinteriors of their mouth portions equipped with lulgs orthread-segments. It may be added t at in the construction hereinillustrated the rotary mold-carrier is equipped with revolublemold-supports which serve to invert the molds and then right them as themolds are carried in their orbit; a mandrel is associated with eachmold, the mandrel being provided with sheathable levers which have theedges of their upper end portions equipped with recesses which providethe matrices in which the lugs or threadsegments are formed; a localmandrel-elevating device is provided at or near the glass-chargingstation, this deviceserving to elevate the mandrels, in. turn, beforethe glass-charging operation is performed; and a local mandrel-loweringdevice is provided for lowering the mandrels, seriatim, as the moldspass in turn, from the glass-charging station to the bubble-blowingstation. At the intermediate station shown in Fig. 1, the glass-chargingoperation is performed after the mandrel has been elevated; and at thenext station the bubble-blowing operation is erformed after the mandrelhas been lowere At the intermediate station mentioned, a blow-head isemployed to force the glass down into the lower portion .of the mold sothat it will form properly about the tip of the mandrel in the neckportion of the mold. Bot-tle blanks, or parisons, are formed in themachine illustrated in the accompanying drawings; the molds are, in theoperation of the machine, inverted and opened and the parisons orbottleblanks are transferred to a blowing machine; andthe finaloperation of blowing the bottle is performed in the machine lastreferred to, no illustration ofsuch machine being required for thepurpose of the description of the present invention.

In the embodiment of the invention illustrated, A represents the base ofthe frame, from which rises a stationary shaft or column A; B, a rotarymold-carrier having revolubly mounted thereon a series of moldsupports Bupon which are mounted molds B B a large gear through themedium of whichthe mold-carrier B is rotated, so that the molds will be carried in anannular path or orbit; C and C, stationary cams which serve to open andclose the molds; D, a stationary bevel-gear segment which serves torotate the mold-supports and invert and then right the molds as they arecarried through their orbit; E, a tubular mandrel associated with eachmold, each mandrel being equipped at its lower projecting end with ahead or cam-member E; F, a mandrel-elevating device located at theglass-charging station; G, a mandrel-lowering device located between theglass-charging station and the bubble-blowing station; H, a stationarycam serving to hold the mandrel in the lowered position during thebubble-blowing operation; I, a bubble-blowing device located beneath thepath of the molds; and J, a blow-head carried by the upper portion ofthe stationary column A and disposed above the path of the molds, theblow-head 'J being located at the glass-charging station.

The frame, which comprises the base A i and column A, may be of anysuitable con struction. The fixed center column A serves as an axisabout which the mold-table B, actuated by the gear B turns; and thecolumn A serves also to support certain mechanisms, including theblow-head which is employed for blowing the glass down into the mold sothat it will form properly about the tip of the mandrel in the neckportion of the mold. The blow-head J employed for this purpose is of theusual construction, and operates in the usual manner.

J The mold-table is given an intermittent or step-by-step movement inany desired manner. The mold-carrying means comprises the table B andthe series of mold.- supports B arranged thereon. Each mold.- supportcomprises a hollow trunnion or gudgeon 1 and a disk or face-plate 1formed integrally therewith. The hollow trunnion 1 is journaled in adivided bearing-box 2 which is securely fastened to the table B.

Each mold B comprises a pair of main mold sections 3 and a pair ofring-mold sections 3. These sections meet in a vertical plane and areprovided with arms 3? and 3, respectively, which are connected at theirinner ends with a pivot 4 carried by lugs 4 which project from theface-plate 1. Thus, the mold sections are capable of separating at aplane containing the axis of the mold.

The mandrel or plunger E associated with each mold works through asleeve 5 which is secured in a tubular head 5 carried by studs 6 whichproject from the face-plate 1. The shank of the bracket which comprisesthe ring 5 is equipped with perforated lugs 5 which are mounted on thestuds 6. The tubular portion 5 of the bracket is thus staunchlysupported on the studs 6 and may *be adjusted thereon, if desired. Anysuitbore 8.

able securing means (not shown) may be employed. The tubular portion 5of the bracket is located directly below the mold and is provided at itsupper portion with a peripheral flange 5 which interlocks with flangeswith which the ring sections 3 of the mold are provided. The sleeve 5 issecured in the ring or tubular member 5 in any desired manner.

' Above the sleeve 5 is a chamber 7 which communicates through a passage7* with a mold cavity. The mandrel-tip is adapted to project snuglythrough the passage 7. The mandrel-tip is designated 8. It is providedwith slots 8 in which are mounted a pair of levers 9. The levers 9 aremounted on the pivots 10 which pass through perforations 10 in thelevers, the end portions of the pivots being supported in the walls ofthe mandrel-tip 8. The mandrel-tip is provided at its lower portion withan enlarged bore 8 and above this bore with a smaller The mandrel isprovided with a tubular shank 11 with the lower end of which the disk orcam E is securely connected. The shank 11 has an enlarged upper end 11which is adapted to work in the enlarged bore 8 with which themandrel-tip is provided. Extending horizontally through the head orenlarged portion 11% is a stud 12 whose extremities project and work invertical slots 13 with which the walls surrou iding the bore 8" of themandrel-tip are provided. The smaller bore 8 of the mandrel-tip servesas a chamber for a coil spring 14 which is confined between themandreltip and the head 11 of the tubular shank 11.

Thus, there is lost-motion connection between the tubular shank 11 andthe mandreltip; and the spring 14 tends to hold the mandrel-tip in theelevated position with respect to the mandrel shank shown in Fig. 6.

The lower ends of the lug-forming levers 9 are provided with cams 9which coact with cam recesses 15 with which the head 11 of the tubularshank 11 is provided. \Vhen the mandrel-tip 8 is projected withrelation" to the mandrel-shank, the cams cause the upper ends of thelevers to be sheathed within the slots of the 1nandrel= tip, as shown inFig. 6. The outer edges of the upper portions of the levers 9 areprovided with recesses 9" which are adapted to form internal lugs orthread-segments on the inner surface of the bottle mouth, as shown inFig. 7. The upper portion of mandrel-tip is suitably shaped. to give thedesired shape to the mouth of the bottle} and the outer edges of theupper portions of the levers 9 are shaped to correspond with the shapeof the mandrel-tip when the levers are in the operative position. Themandreltip 8 has a reduced portion 8 which is adapted to fit in theopening 7 leading to the mold cavity, when the mandreltip is in theelevated position. The levers are corres pondingly shaped to completethe contour when the levers are in the operative position. Themandrel-tip is further provided with a horizontal shoulder 8 which isadapted to strike against the bottom of the mold and limit the upwardmovement of,

the mandrel-tip when the mandrel is elevated.

Through the tubular part 5* and the sleeve 5 extends a plunger guide 16in which works a'spring-pressed pointed plunger 16 which is adapted toengage a lateral recess 17 with which the mandrel-tip 8 is provided. Thepointed tip of the plunger 16 is adapted to work in a vertical slot 18when the mandrel-tip is forcibly moved.

The glasscharging station is designate S and-the bubble-blowing stationis designated S The mandrel-elevating device F is located beneath thepath of the molds at the glass-charging station. The device F preferablycomprises a plunger 19 operated by a piston 19 located in the cylinder19*. Theplunger 19 is equipped with a head 19 which has a channel orT-slot 20 extending horizontally therethrough. As each mold is carriedto the glass-charging station, the cam-disk E of the associated mandrelenters the channel 20 as shown in Fig. 6. When the machine comes torest, the plunger 19 is elevated to elevate the mandrel to the positionshown in Fig. '7. After the glasscharging operation the charged mold iscarried to the bubble-blowing station, the camdisk E sliding out of thechannel 20 as the mold 13 carried away from the charging station.

As the mold approaches the bubble-blowing station, the cam-disk Eengages the mandrel-lowering device G. The device G is mounted on astandard G carried by the frame-base A. The device G is provided with aninclined T-slot 21 which affords overhanging inclined flanges 21. Thecamdisk E of the mandrel-shank passes beneath the inclined flanges 21and the mandrel is thereby Withdrawn. In the first portion of thedownward movement of the mandrelshank, the shank moves with relation tothe mandrel-tip, thereby actuating the levers and sheathing the upperportions of the levers. This withdraws the levers from en gagement withthe lugs or thread-segments formed on the interior of the bottle mouth.In the final portion of the downward movement of the mandrel-shank, themandrel-tip is withdrawn, so that the passage '7 which leads to thevmoldcavity is open to admit air to the mold.

At the bubble-blowing station, the bubble blow-head I is elevated untilits tip engages the conical -recess 22 at the lower end of themandrel-shank. Air is admitted to perform the bubble-blowing operation,through a pipe 23. The bubble blow-head I is actuated by the piston 24confined in a cylinder 25. At the bubbleblowing station, the cam-disk Eof the mandrel-shank passes beneath the stationary cam H, so that themandrel will not be caused torise when the bubble-blowing device isforced against the lower end of the/shank.

The rotary table or mold-carrier is interployed in the glass-chargingoperation if desired; and L represents a shears for cutting off theglass.

The ano-lds are opened and closed by means of plu'ngers 26 operated bythe cams U and C. Each plunger 26 is connected, by links 27, with themold sections.

On the hollow trunnion 1 of each moldsupport is secured a bevel-gear 28which 'co'acts with the stationary bevel-gear D to.

invert and right the molds. The rack D is supported in any suitablemanner (details not shown). The molds may be maintained in their normalupright position by any suitable expedient (not shown). If desired,frictional contact between the tram nion 1 of the mold-support and thesectional bearing-box may be such as to cause the bearing-box to gripthe trunnion of the mold-support sufficiently to 'maintain the mold inits upright position during the passage of the mold. from one station toanother. Any suitable or usual locking device may be employed forreleasably locking the molds in upright position if desired. Suchlocking device is not illustrated, however.

The operation may be briefly stated as follows:

The mold-table B is given an intermit tent movement of rotation in theusual manner, the rotation being efi'ected throu h the medium of thelarge gear B W en a mold reaches the glass-charging station, the device15 operates to elevate the mandrel from the position shown in Fig. 6 tothe po- &

As the mold leaves the glass-charging station, the cam-disk E of themandrel moves out of the channel or T-slot 20 of the man'-drel-elevating device. During the passage of the mold to thebubble-blowing station, the cam-disk E rides beneath the inclinedflanges 21 of the device G thereby lowering the mandrel. At thebubble-blowing station, the stationary cam H serves to hold the mandrelagainst elevation during the bubble-blowing operation. i

The improved machine operates in the same automatic manner as domachines of this type employed for making bottles having plain, orunthreaded interior mouth surfaces; and the improved machine is capableof the usual large output of an automatic machine of this type. Thus,bottles of merchantable character can be produced economically and inlarge quantities, such bottles being provided in their mouth portionswith internal threads.

Fig. 2 illustrates a modified form of mandrel-elevating device. Thisdevice is designated F. It comprises a cam-member having aninclinedportion 29 and a hori zontal port-ion 29 The device F is mounted on astandard F 2 carried by the base A of the main frame. The device F is solocated with relation to the glass-charging station that the cam-disks Eof the mandrels will ride over the inclined portion 29 and onto thehorizontal portion 29*, therebv elevating'each mandrel, in turn, and holing the mandrel elevated, during the glasscharging operation. After theglass-charging operation, the cam-disk E of the mandrel rides off thehorizontal portion 29 of the cam F as the mold is carried towards thebubble-blowing station.

If desired, the cam H may be dispensed with and some other suitable provision made for holding the mandrel in lowered position during thebubble-blowing operation. This may be effected by means of a suitablenumber of spring-pressed catches, such as the catch 16; or othersuitable means may be employed. The catch 16 is adapted to releasablyhold the mandrel-tip in either the elevated or the. depressed position.The catch serves, furthermore, to prevent idle movement or shifting ofthe mandrels in. their bearings during the inverting and righting of themolds.

In- Fig. 7. 30 designates the lugs which are formed in the interiorofthe' container mouth 30?. As has been stated, these lugs may be of anysuitable form adapted to engage -the threads or thread-segments of astopper. It ispreferred to employ at least two of the lug-formingsheathable levers 9.

While the invention is illustrated in connection with an automaticmachine of the type in which invertible molds are employed, it may beused in connection with any automatic or semi-automatic machine of thetype in which molds are carried in an annular path, each mold havingassociated therewith, a mandrel provided with sheathable or collapsiblemeans for forming the lugs on the interior of the containermouth, themandrels being raised and lowered automatically in the. operation of themachine.

The foregoing detailed description has been given for clearness ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, it being the intent to claim the invention as fully aspossible in view of the prior art.
